Salesforce
Salesforce.com is a customer relationship management platform that gives all company departments (marketing, sales, commerce, and service) a single, shared view of every customer. Once Salesforce is integrated with Docupace, company employees are able to see from within the Salesforce interface those documents and work items, that are being processed in the Docupace system, as well as open Docupace to create new client records and client accounts for ongoing business.
